We are online and connected almost all the time. We might be shopping, relaxing or interacting with friends, paying bills, or learning a new skill. Regardless of our activity online, as long as we manage to stay protected when it comes to cyber threats we should be fine. You may already be aware of some common cyber threats, but do you have at your disposal the free security tools you can use for your online protection?

Free Online Security Tools

Password strength checker

For each online service that we’re using a password is required, therefore a short discussion about the importance of password hygiene should be in order.

Good password hygiene most common practices include, but are not limited to, selecting passwords that are not obvious, perfunctory, or common, selecting a unique password for each account, avoiding the temptation to write passwords for easy recall, and avoiding the temptation to share passwords with others for convenience.

Bad password hygiene is responsible for countless data breaches and individual account takeovers, and security administrators routinely invest time and effort to educate users about bad password hygiene and its consequences.

It’s important to note that data breach detection tools take cybersecurity a step further by monitoring activity throughout an entire IT network in real-time, therefore being able to give you comprehensive visibility to the key data points your team needs to know or even begin the remediation process immediately with automated workflows that your organization pre-configures.

Free Antivirus Software

You might believe that you are being careful when online and visiting reputable sites. Maybe you are only downloading from official sources like the Windows Store, or iTunes, but here’s the thing: You’re never truly protected when going online completely unprotected, therefore you still need antivirus software, as out there are all kinds of miscreants that just want nothing more than to steal and cause mayhem by getting inside your PC. It sounds scary, but because much of our lives are now conducted online, the threat is as real as ever.

1. Microsoft Defender

The free Microsoft Defender Antivirus software running on Windows 10, offers you a malware protection safety net as the free antivirus program is built into Windows and it’s turned on by default. Fortunately, this free antivirus solution will cover the basics of internet security. You should note that Windows 10 will automatically disable its own Windows Defender antivirus if you install a third-party antivirus.

2. ClamAV

5. SUMo

SUMo is great but you’ll have to upgrade to a paid version to take full advantage of any automatic updating. There are plenty of reasons to stick with the free version though; if you’re not worried about initiating manual updates this software may be just what you were looking for. One really cool perk to the SUMo software is that it can search for beta versions of software on your computer. That’s not a claim many free software updaters are able to make in full confidence.

SUMo offers the possibility of blacklisting certain programs you don’t want to come up in your list of pending updates. If you like SUMo, be sure to try out their sister program, DUMo, for driver update checks.

Wrapping Up…

As it is in any competitive field in the cybersecurity game the bad guys constantly try to outrun the good guys and the other way around.

Some food for thought – at the end of the day no single tool is bulletproof. One should not relax and rely on one software alone or on a single app to keep you safe as they all have their flaws, all have their vulnerabilities.

It is not a bad idea to try to think and act like a journalist – question and be suspicious about everything you receive or run into the digital world and looks slightly suspicious.

Check once, check twice check thrice may you need to do so before you act or click on it; be sure you are not engaging anything that looks fishy.

Stay on the safe side of digital life!

Great article and very informative. Thank you for putting in all the hard work of researching what’s best to use when it comes to just over all internet security

I like this blog! Thank you for sharing with us.

Thank you! Happy you found the info helpful.

Thanks This is an awesome list! I do think that you might add Offensive Security’s blog, because it updated frequently with all their cool stuff.

I want to be covered so I can go on dark web

I’d recommend setting up atlas VPN for small business owners. Its good service for free, no data limit, but mind that it’s only available on androids and iphones. Also Surfshark is probably the best paid option, I think they’re doing business promotions right now, so its worth checking it out as well. Be sure to check the reviews before picking tho

I’d say ESET AV, VPN 360, Datplan Cyber Control, Net flow analyser, keeper for business

Good information. Lucky me I recently found your blog
by accident (stumbleupon). I’ve bookmarked it for later!

What’s up, I want to subscribe for this web site to take latest updates,
therefore where can i do it please assist.

Hello and thanks for reaching out! If you want to stay informed about the latest articles and infosec news we publish on the blog, feel free to subscribe to our newsletter here:

Great article, thank you for the lists; have a question. Was reading on another review that Heimdal was good but more useful as accompanied security software to another anti virus software. This seems redundant since two doesn’t equal better but never hurts to ask. I see on your list that Dragon a COMODO product is a good browser to use so would HEIMDAL and COMODO Internet Security Complete 11 work well together, complement each other or be redundant?

There is a bunch of absolutely free useful security tools here: . Any of them worth including in the list here. Nice work anyway)

Nice Article, very useful information.

Thank you so much for your kind feedback!

I propose t add one more redirect checker tool –
It allows to trace requests from different devices and different locations.

thank you for sharing and narration.

Heimdal frequently mentions “Malvertising” as a type of attack. Your list of free tools should include “Hostsman”. HostsMan is a freeware application that lets you manage your Hosts file with ease to block malicious ads, and malware domain sites. I encourage Heimdal to test this software and include it in your free security tools list. You should also include Keepass Password Safe, version 2 in your password managers list.

Thanks for doing this. Now I don’t have to compare 50 different security software suites.

really enjoyable
glad I read it

A very important topic in these terrible times (Ransomeware)

A very good and detailed article. many thanks, fav’ed!
